DEVICE FOR DISTRIBUTING AIR.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed April 16, 1912. Serial No. 691,080.

T0 till whom it may concern:

Be it known that I, ADOLPHE E. Bossr'i, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inDevices for Distributing Air, of which the following is a specification.

My invention relates to a device for dis tributing air for heating,ventilating and cooling purposes and it relates more particularly to asimple and inexpensive apparatus whereby the air for heating,ventilating and cooling purposescan be conducted and distributedthroughout a room or other confined space.

The object of my invention is to provide a simple and inexpensiveapparatus whereby the previously heated or cooled or fresh air may becarried to the desired parts of the room or other confined space anddistributed evenly and uniformly and projected without appreciabledrafts in the necessary direction to thereby secure the most eflicientdistribution of the air for the required purpose.

The nature and characteristic features of my invention will be morereadily understood from the following description taken in connectionwith the accompanying drawings forming part hereof, in which:

Figure 1 is a front elevation, partly in section, of an apparatus fordistributing air embodying the main features of my present invention;and Fig. 2 is a transverse section thereof, enlarged, taken on the line22 ofFig. 1.

Referring to the drawings, in the particular embodiment of. my inventiontherein shown, 3 is a vertical supply pipe leading from the source ofsupply or from the heat- .ing or cooling apparatus, not shown. The pipe3 is provided at its top with a branch 4., preferably circular in crosssection, and

having journaled therein a short pipe or nipple 5. The pipe or nipple ispreferably made to fit snugly within the branch 4 so as to afford acertain amount of frictional resistance to prevent improper rotation ofthe distributing conduit proper, yet permitting the same to be adjustedwhen desired. On the projecting end of the pipe or nipple 5 is mountedone end of the dis tributing conduit 6 which is preferably made of sheetmetal and having its main or body portion of circular cross section. Inthe periphery of the-conduit 6 there is provided a slot 7 for the egressof the air. This slot is preferably formed by continuing a portion ofthe metal of which the conduit is composed tangentially for aconsiderable distance to provide a wing or apron 8 which is alsopreferably curvilinear in cross section. The inner portion of the wingor apron 8 forms one of the margins of the slot 7 and the other marginof said slot is formed by a lip 9 extending in a direction substantiallyparallel to that of the wing 8, but extending to a'lesser extent.

One end of the distributing conduit is mounted on the pipe or nipple 5while the other end'is supported on a similar pipe or nipple 10 which issnugly journaled in a socket 11 or other suitable supporting device. Itwill be seen that the distributing conduit 6 is therefore capable ofrotation in its supporting structure so that the slot 7 and the adjacentwing 8 may be rotated and brought to any desired angular position.

If desired the supporting pipe or nipple 5 may be provided with asprocket wheel 12 over which may be mounted a chain 13 for the arbitraryrotation of the conduit 6 at any desired time and from any convenientlocation. At each end of the conduit 6 there is preferably arrangedWithin the slot 7 a spacing block 14 which also serves to prevent theair from escaping sidewise. If desired these spacing blocks may also besoldered or otherwise secured within the slot 7 at various places alongits length to stiffen the structure and prevent distortion of the samewhen subjected to torsional strain during the adjustment.

It should be noted that the slot 7 for the egress of the air is of arelatively small size so that theair will be distributed uniformlythroughout the length of the conduit and that the wing 8 will serve toguide the air as it passes from the slot 7 and distribute the same inthe desired direction in a smooth and uniform manner, but withoutobjectionable drafts. For example when the device is used in thedistribution of cold air, the conduit is usually arranged near the topof the room or chamber,'-and it is obvious that if the wing 8 was notprovided the cold air would immediately descendinstead of beingdistributed uniformly into the body of warm air at the top of the roomor chamber. The wing 8 however prevents this immediate descent of thecold air as it will be projected by the lip 9 over the upper surface ofthe wing 8 where it will to a considerable extent intermingle with andreduce the temperature of the warmer air and thus efiectually producethe desired cooling effect throughout the room without causingobjectionable drafts in any particular direction. Of course when thedevice. is used for the dissemination of warm air' it will be placed ininverted position at the bottom of the room or chamber resulting in theincrease of temperature in substantially the same manner.

Having thus described the nature and characteristic features of" myinvention,

what I claim as new and desire to secure by,

Letters Patent is 1. A device for distributing air comprising a conduithavinga narrow longitudinal slot for the egress of the air, and a wingextending outward from one of the margins of said slot.

2. A device for distributing air com rising a conduit having a narrowlongitu inal slot for the egress of the air, a wing extending outwardfrom one of the margins of said slot, and a -outwar from the otherWitnesses:

lip extending outward from the other margin of said slot. 3. A devicefor istributing air com rising a conduit having a narrow longitu inalslot for -the egress of the air,a wing extending outward tangentiallyfrom one of the mar 'ns of said slot, and a lip extending margin of saidslot in the same general direction as said wing but to a lesser extent.

4. A device for distributing air com rising a conduit having a narrowlongitu inal slot for the egress of the air, a wing extending outwardtangentially from one of the margins of said slot, a supily pipe, meansfor supporting the slotte conduit from said "supply ipe in such manneras'to permit rotation 0 said conduit to vary the angular location of theslot and projecting wing.

In testimony whereof I have hereunto signed my name in the presence oftwo witnesses.
